The acoustic soundtrack titled “Falling in Love” captures the nervous but wonderful feelings of unintentionally falling in love. Fellow “Produce 101 Season 2” contestant Kwon Hyun Bin currently appears in the drama as well.

Kim Seong Ri worked with hit producer Major Leaguer for the OST and participated in writing the lyrics as well. The two previously worked together on OST “When You Look Back” for the KBS drama “Rose of Sharon Is Blooming.”

Ahead of their debut, RAINZ members are showing off their vocal talents by participating in drama OSTs such as JTBC’s “Woman of Dignity,” KBS’s “Rose of Sharon Is Blooming,” and MBC’s “Hospital Ship.”
